wifi-menu

wifi-menu is a nice curses interface for making wireless connections with the netctl system. It makes it very simple.

wifi-menu wlp3s0	# add connection (to autoconnect to)

troubleshooting

Wifi Dropping

This is not specific to netctl/netcfg, but there is a bug with the intel wifi drivers that causes it to drop wifi connections.

# test to see if fixes problem
modprobe iwlwifi 11n_disable=1 swcrypto=1

# /etc/modprobe.d/iwlwifi.conf
